If the husband is seriously ill and the wife ignores him, can he sue?

You can sue him. Our country's law requires both husband and wife to take care of and support him.

Therefore, the husband is seriously ill and the wife is indifferent. It is entirely possible to sue her in court. You can sue your wife for desertion.

The vows we made when we got married were not false. We swear that we will never give up whether we are rich or poor. Don't think this sentence is just talk. The law clearly stipulates that both husband and wife have the obligation to take care of and support him. If the obligor has no source of income or is sick, the other party must take care of and raise him.
